CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation of U.S. patent application Ser. No. 11/677,553 filed Feb. 21, 2007 by Walter et al., entitled “Method and Apparatus for Authenticating a Communication Device.” All sections of the aforementioned application are incorporated herein by reference in its entirety.

FIELD OF THE DISCLOSURE

The present disclosure relates generally to authentication techniques, and more specifically to a method and apparatus for authenticating a communication device.

BACKGROUND

Identity theft over the Internet has been and continues to be an issue faced by service providers and its subscribers. As common communication devices such as house or office phones migrate to the Internet for data as well as voice communications, a risk arises that private information associated with these communication devices (e.g., a Media Access Control address, serial number, etc.) can be stolen and used to program counterfeit devices to access communication services of subscribers without authorization.

A need therefore arises for a method and apparatus for authenticating a communication device.

DETAILED DESCRIPTION OF THE DRAWINGS

Embodiments in accordance with the present disclosure provide a method and apparatus for authenticating a communication device.

In a first embodiment of the present disclosure, an authentication system can have a controller element that receives from a communication device over a packet-switched network a terminal ID and a request to authenticate said communication device, generates a first registration ID responsive to the request, stores the first registration ID and a first communication identifier, transmits the first registration ID to the communication device, receives from an interactive response system a second communication identifier and a second registration ID that the interactive response system received during a communication session with the communication device over a circuit-switched network, and authenticates the communication device in response to detecting a match between the first and second communication identifiers and the first and second registration IDs.

In a second embodiment of the present disclosure, a computer-readable storage medium in an interactive response system can have computer instructions for receiving from a communication device over a circuit-switched network a first registration ID that was supplied to the communication device over a packet-switched network by an authentication system, retrieving from signaling information of the circuit-switched network a first communication identifier associated with the communication device, and submitting the first communication identifier and the first registration ID to the authentication system for authenticating the communication device in response to detecting a match between the first communication identifier and the first registration ID and a second communication identifier and a second registration ID stored in the authentication system.

In a third embodiment of the present disclosure, a communication device can have a controller element that transmits to an authentication system over a packet-switched network a terminal ID and a request to authenticate said communication device, receives from the authentication system a first registration ID, and transmits to an interactive response system over a circuit-switched network the first registration ID. The interactive response system can retrieve from signaling information of the circuit-switched network a first communication identifier associated with the communication device, and submit the first communication identifier and the first registration ID to the authentication system for authenticating the communication device in response to detecting a match between the first communication identifier and the first registration ID and a second communication identifier and a second registration ID stored in the authentication system.

In a third embodiment of the present disclosure, a method can involve authenticating a communication device by collectively processing one or more authentication steps in a packet-switched network and one or more authentication steps in a circuit-switched network.

FIG. 1 depicts an exemplary embodiment of a communication system 100 for authenticating a communication device 108. The communication system 100 can comprise a Packet-Switched (PS) network 101, a Circuit-Switched (CS) network 103, an authentication system 102 and interactive response system 104. The PS network 101 can comprise a number of common network elements (e.g., routers) that transport packetized messages between end points of the communication system. The PS network 101 can operate according to any number of communication protocols including without limitation an Internet Protocol (IP), Multi-Protocol Label Switching (MPLS), Asynchronous Transfer Mode/Frame Relay (ATM/FR), and combinations thereof. The CS network 103 can comprise common circuit-switched network elements that operate as a Public Switched Telephone Network (PSTN) for transporting digitized messages between end points of the communication system 100.

The authentication system 102 can utilize common computing, communications, and mass storage media technologies (such as found in a server or mainframe computer) to perform tasks associated with authenticating the communication device 108 by way of the communication system 100. The authentication process can be used as a deterrent to counterfeiters attempting to gain access to services of the communication system 100 by way of counterfeit communication devices.

The interactive response system 104 also utilizes common computing, communications, and mass storage media technologies and operates with the authentication system 102 to perform the authentication process. The interactive response system 104 can communicate with the communication device 108 over the CS network 103 and process Dual Tone Multi-Frequency (DTMF) signals generated by the communication device 108. The interactive response system 104 can represent a common Interactive Voice Response (IVR) system or other suitable processing technology.

Communications between the authentication system 102 and interactive response system 104 can take place over the PS or CS networks 101, 103. Alternatively, said systems 102-104 can be integrated in which case they would be logical units operating in one computing platform utilizing the resources available to them to communicate with the communication device over the PS and CS networks 101, 103.

The communication device 108 can be embodied in any device occupied in a building (commercial or residential) 106 that communicates over the PS and CS networks 101, 103 by way of packet-switched and circuit-switched communication interfaces integrated therein. FIG. 2 depicts an exemplary embodiment of the communication device 108. The communication device 108 can comprise a wireless or wireline transceiver 202, a user interface (UI) 204, a power supply 216, and a controller 203 for managing operations of the foregoing components.

The transceiver 202 utilizes common circuit-switched and packet-switched communication technologies. Wireline access technologies used by the transceiver 202 can include, for example, cable, xDSL, Public Switched Telephone Network (PSTN), and so on. Singly or in combination with the wireline technology, the transceiver 202 can support singly or in combination any number of wireless access technologies including without limitation Digital Enhance Cordless Telecommunications (DECT), Bluetooth™, Wireless Fidelity (WiFi), Worldwide Interoperability for Microwave Access (WiMAX), Ultra Wide Band (UWB), software defined radio (SDR), and cellular access technologies such as CDMA-1X, W-CDMA/HSDPA, GSM/GPRS, TDMA/EDGE, and EVDO. SDR can be utilized for accessing public and private communication spectrum with any number of communication protocols that can be dynamically downloaded over-the-air to the communication device 108. Next generation wireline and wireless access technologies can also be applied to the operations of the transceiver 202.

The UI element 204 can include a keypad 206 with depressible or touch sensitive keys and a navigation element such as a navigation disk, button, roller ball, or flywheel for manipulating operations of the communication device 108. The UI element 204 can further include a display 208 such as monochrome or color LCD (Liquid Crystal Display) which can be touch sensitive for manipulating operations of the communication device 108 and for conveying images to the end user of said device, and an audio system 210 that utilizes common audio technology for conveying and intercepting audible signals of the end user.

The power supply 216 can utilize common power management technologies such as replaceable batteries, supply regulation technologies, and charging system technologies for supplying energy to the components of the communication device 108 and to facilitate portable applications. Depending on the type of power supply 216 used, the communication device 108 can represent an immobile or portable communication device. The controller 203 can utilize computing technologies such as a microprocessor and/or digital signal processor (DSP) with associated storage memory such a Flash, ROM, RAM, SRAM, DRAM or other like technologies for controlling operations of the communication device 108.

The communication device 108 can represent a single operational device or a family of devices configured in a master-slave arrangement. In the latter embodiment, the components of the communication device 108 can be reused in different form factors for the master and slave terminal devices 100. The communication device 108 can also be represented by any number of communication devices including without limitation a laptop computer, a desktop computer, a cell phone, a personal digital assistant, a set-top-box (STB), or a cordless phone just to name a few. An end user can also utilize more than one type of communication device 108 and migrate between communication devices when desired. Additionally, each of the communication devices 108 can be addressed by one or more communication identifiers for establishing real-time (e.g., voice) and/or non-real time communications (e.g., text or recorded speech).

FIG. 3 depicts an exemplary method 300 operating in portions of the communication system 100. Method 300 begins with step 302 in which a communication device 108 transmits a terminal ID and an associated authentication request to the authentication system 102 over the PS network 101. Step 302 can occur, for example, each time the communication device power cycles, at periodic intervals as directed by the authentication system 102, or as an autonomous function of the communication device 108. The terminal ID can comprise any suitable form of identification such as, for example, a Media Access Control (MAC) address of the communication device 108 or a MAC address of a residential gateway in the building 106.

In step 304, the authentication system 102 can be programmed to search through a database managed thereby using the terminal ID as an index therein to determine if the communication device 102 has previously been authenticated and re-authentication is not required. If the communication device 108 has been previously authenticated and re-authentication is not required, the authentication system 102 proceeds to step 306 where it submits an error message to the communication device 108 indicating that the request is erroneous. If, on the other hand, the communication device 108 has not been previously authenticated or requires re-authentication, the authentication system 102 proceeds to step 308 where it generates a registration ID.

The registration ID can be a random number generated using common techniques. For instance, the terminal ID can be used as a seed for generating the random number from a common random number generation method. Alternatively, the registration ID can represent any arbitrary number that can be hard to guess. Thus, the registration ID does not have to be limited to random numbers. It can be generated by hashing algorithms (such as Message Digest 5 or MD5; or a Secure Hash Algorithm or SHA). The MAC address of the communication device 108 along with an encryption key can be supplied to a one-way hash to generate an undistinguishable string of characters.

From the foregoing techniques it would be evident to one of ordinary skill in the art that the registration ID can be represented by any common or future coding scheme suitable for identification purposes.

In step 310, the authentication system 102 can store (for later use in the authentication process) the registration ID with a communication identifier associated with communication services supplied to the building 106. The communication identifier can conform to an E.164 International Telecommunications Union (ITU) standard for common PSTN applications. Alternatively, in an embodiment where the communication system 100 in whole or in part operates according to an IP Multimedia Subsystem (IMS) standard, the communication identifier of the communication device 108 can be represented by a Session Initiation Protocol Uniform Resource Identifier (SIP URI) or a Telephone (Tel) URI. The communication identifier can be programmed into the authentication system 102 at a time when an end user subscribes to communication services of the communication system 100 for a communication link in the building 106.

In step 312, the authentication system 102 can be programmed to transmit the registration ID to the communication device 108. In this step, a communication identifier (e.g., an 800 number) of the interactive response system 104 can also be transmitted if not already preprogrammed in the communication device 108. The communication device 108 in response establishes communications over the CS network 103 using the communication identifier of the interactive response system 102 and transmits in step 314 the registration ID to the interactive response system utilizing DTMF tones.

Alternatively, the registration ID transmitted in step 314 can represent a sound-based transmission. For example, DTMF tones can be used to create tonal combinations supporting HEX or binary encoding. In addition, one could use a modem to transmit more traditional data in which case the interactive response system 104 can be supplemented with a modem interface. If the interactive response system 104 supports speech recognition, the communication device 108 can also generate synthesized speech to relay the registration ID.

From the aforementioned transmission techniques it would be evident to one of ordinary skill in the art that any transmission method used over the CS network 103 can be utilized to convey the registration ID.

In step 316, the interactive response system 104 retrieves from signaling information of the CS network 103 using common techniques a communication identifier associated with the communication device 108 (e.g., caller ID retrieved from an automatic number identification feature). In step 318, the interactive response system 104 transmits to the authentication system 102 the registration ID (e.g., the random number) and the communication identifier (caller ID) of the communication device 108 collected in step 316. The transmission of step 318 can take place over the PS or CS networks 101, 103.

The authentication system 102 in step 320 compares the registration ID and the communication identifier supplied by the interactive response system 102 to those stored in its database which can be indexed by the communication identifier supplied in step 318. If a match is not found, the authentication system 102 proceeds to step 324 where it submits an error message to the communication device 108 indicating, for example, that the authentication process has failed.

If on the other hand a match is found, the authentication system 102 proceeds to step 326 where it transmits to the communication device 108 provisioning information. The provisioning information can include among other things the communication identifier of the communication device 108 (if not already known by said device) and a dial plan that provides an instruction guide to communications services subscribed by the end user residing in the building 106. The dial plan can provide the communication device 108 for instance dialing instructions for 7, 10 or 11 digit dialing for the services supplied to building 106. In an embodiment in which the communication system 100 supports IMS services, the dial plan can represent an instructional guide for the communication device 108 corresponding to communication operations for said system.

As a supplemental embodiment, the authentication system 102 can be programmed to request that the communication device 108 re-authenticate on a periodic basis to reduce the likelihood of unauthorized usage of the communication system 100 by counterfeit communication devices. For example, in step 328 the authentication system 102 can be programmed to monitor restart times for submitting re-authentication requests to communication devices 108 (e.g., once per hour, once per day, once per week, etc.). When the restart time is triggered, the authentication system 102 proceeds to step 330 where it transmits a re-authentication request to the communication device 108. This prompts the communication device 108 to repeat method 300. Alternatively, the communication device 108 can be programmed to re-authenticate on its own. In this embodiment, step 304 can be modified to recognize a need for re-authentication at periodic intervals in which case step 306 would not occur unless the re-authentication request submitted by the communication device 108 is too early.

It is unlikely that a counterfeit communication device can gain access to communication link closest to a building 106 housing a legitimate communication device 108. It follows that a counterfeit communication device communicating over the CS network 103 while outside the reach of building 106 will not share the same communication identifier (caller ID) as a communication device 108 in the building. Consequently, a proper communication identifier cannot be supplied to the interactive response system 104 in step 316, which inevitably leads to an authentication failure in step 322. Utilizing the exemplary two factor registration technique of method 300, a service provider can prevent unauthorized access to the communication system 100 and therefore protect its subscribers from an unsuspected theft of the terminal ID of the communication device 108.

Upon reviewing the embodiments disclosed, it would be evident to an artisan with ordinary skill in the art that said embodiments can be modified, reduced, or enhanced without departing from the scope and spirit of the claims described below. Accordingly, the reader is directed to the claims section for a fuller understanding of the breadth and scope of the present disclosure.
